Kennedy Appoints Vaccine-Skeptical OB-GYNs to CDC's Key Advisory Panel Amid Ongoing Immunization Policy Shifts

On January 13, 2026, U.S. Health and Human Services Secretary Robert F. Kennedy Jr. announced the appointment of two obstetrician-gynecologists, Dr. Adam Urato and Dr. Kimberly Biss, to the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP). This move comes seven months after Kennedy reconstituted the entire 19-member panel in June 2025 by dismissing all prior members, aiming to enhance transparency, reduce perceived conflicts of interest, and restore public trust in vaccine recommendations. The ACIP plays a pivotal role in advising the CDC on vaccine safety, efficacy, and immunization schedules, influencing federal guidelines, insurance coverage, and public health practices nationwide.

Appointees’ Backgrounds and Expertise

Dr. Adam Urato, a maternal-fetal medicine specialist, has affiliations with Harvard Medical School and Tufts University, where he has focused on high-risk pregnancies. He has publicly questioned CDC guidance on COVID-19 vaccines for pregnant women, arguing that safety data was insufficient at the time of initial recommendations.

Dr. Kimberly Biss, based in St. Petersburg, Florida, has leadership experience at Bayfront Health and has researched COVID-19 vaccine safety in pregnancy. Both physicians bring clinical experience in obstetrics, a field where vaccine recommendations during pregnancy directly impact maternal and fetal health outcomes.

Kennedy praised the appointees, stating, “ACIP serves as Americans’ watchdog for vaccine safety and transparency. Dr. Urato and Dr. Biss possess the scientific credentials, clinical experience, and integrity this committee requires.” HHS Deputy Secretary Jim O’Neill, acting CDC director, added that the panel is aligning the childhood immunization schedule with “gold-standard science,” emphasizing evidence over “dogma.”

ACIP’s Role and Recent Overhaul

The ACIP, which can have up to 19 voting members, reviews vaccine data post-FDA approval and recommends schedules for populations including children, pregnant individuals, and adults. Its guidance shapes CDC policies, which in turn affect school requirements, employer mandates, and insurance reimbursements—impacting over 330 million Americans.

Kennedy’s June 2025 reconstitution marked a sharp departure from tradition, firing 17 Biden-era members amid claims of industry bias. The new panel includes figures like Robert Malone, known for mRNA vaccine critiques, and Martin Kulldorff, a former CDC advisor. Under this group, the CDC revised the childhood vaccine schedule in January 2026, reducing universally recommended vaccines from about 17 to 11 diseases, shifting others like flu, rotavirus, hepatitis A/B, and some meningococcal shots to high-risk or shared decision-making categories. COVID-19 vaccines were removed from routine recommendations for pregnant women and children.

These changes followed Kennedy’s directives to limit mandates, cut mRNA research funding, and prioritize “transparency.”

Public Health Implications

For healthcare professionals, the appointments signal continued scrutiny of pregnancy-related vaccine policies, where data shows vaccines like Tdap and flu shots reduce maternal infections by 50-90% and protect newborns. Consumers may face adjusted counseling: the revised schedule could lower routine childhood vaccinations, potentially increasing outbreaks of preventable diseases like measles, which saw 1,282 U.S. cases in 2019 pre-vaccine hesitancy peaks.

Proponents argue the panel fosters rigorous review, citing pre-2025 ACIP conflicts where members had pharma ties. Kennedy’s “Make America Healthy Again” agenda under President Trump emphasizes this shift toward what officials call unbiased science.

Expert Commentary and Criticisms

Dr. Sean O’Leary, a pediatric infectious disease specialist at the University of Colorado not involved in ACIP, expressed concern: “These appointees have histories of questioning vaccine safety in pregnancy without robust counter-evidence, which could erode trust in proven interventions.” He noted Urato’s claims linking COVID vaccines to miscarriages lack support from large studies showing no increased risk.

The American Academy of Pediatrics (AAP) sued in January 2026 to block ACIP meetings and reverse schedule changes, arguing they deviate from evidence-based standards protecting 73 million U.S. children. Public health leaders worry reduced recommendations might spike vaccine-preventable diseases, as seen in states with lower uptake.

Supporters like Retsef Levi, an ACIP member and MIT professor, counter that the panel demands higher safety thresholds, benefiting vulnerable groups.

Limitations and Broader Context

Critics highlight potential biases: new members’ prior vaccine skepticism may prioritize rare risks over population benefits, where vaccines prevent 2-3 million deaths yearly globally per WHO. Studies affirm COVID vaccines’ pregnancy safety, with millions administered showing miscarriage rates aligning with background levels (10-20%).

Kennedy’s actions reflect Trump administration priorities post-2024 reelection, amid lawsuits from medical groups forming vaccine alliances. Ongoing ACIP reviews of pregnancy vaccines underscore evolving debates.

This development underscores tensions in U.S. public health: balancing caution with access to interventions credited with eradicating smallpox and nearly eliminating polio. For readers, it means monitoring CDC updates and consulting providers for personalized advice, as recommendations influence clinic protocols and insurance.
